The Walls of Jericho

My wife was going through some things belonging to her late mother, and found some jokes she had written down many years ago. Here's one:

The pastor dropped in to visit a little boys' Sunday School class. He asked them a question: "Who tore down the walls of Jericho?"

One of the boys said, "Well, I didn't do it."

The pastor asked the teacher if that was the boy's usual conduct. The teacher answered, "I've know the boy a long time. I believe him to be honest. If he says he didn't do it, I don't believe he did."

The pastor then went to a deacon and told him what happened. The deacon said, "I've known that teacher and the boy for a long time, and I believe them to be honest. If they say he didn't do it, I believe them."

In desperation the pastor went to the chairman of the House and Grounds Committee and told him the story.

"Well," he said, "I know them all and I believe we'd better just go ahead and pay for the damage to the wall and forget about it."
